ii The present invention" is especiallyconcerned with machines of this type equipped with mechanism for building filling Wound bobbins. Usually these machines are equipped with a full bobbin stop motionwhich operates automatically to stop the machine when the filling of the bobbins hasbeen completed. According to; the oomm'on practice, the machine tender startsjup the frame again imme diately after it hasjfbeenlstopped begins at once to wind downthe ring railby hand,

stopping the frame again when the railhas been completely lowered. This results in winding theyarn or thread in a spiral around i the bobbin and then winding few turns of thread or yarn on'th'e base oi tlie bobbin.

.W'itha View reducing the care and labor involved inper orming' this operation, and producing more unifonnresults, ith'as been proposed heretofore to perform-the wind down operation automatically, and .it is the general 'ob ect ofth s nvention to devisea superior}niechanlsm for accomplishlng this resultl' v In my copen' ding applieationTSerial No.

" In the machine showmthering rail is in dicated 'atQjthis rail being supporte dby a ser es of vertical rods, one of which is shown inlfig. 1 zit-3'." The lowerend-of this-rod carries a foot which rests on a roll 4 supported at, the-outer end of an arm '5 which 1 is'secured rigidly to a cross shaft- 6. A

Weight 7also fastened to the cross shaft tends to operate through the eonnetions ustf de{ scribed;tolift'thoring rail'2." The upward movement ofthe ring rail, however, is vcon trolled by'abuilder motion'indicat ed ingen eral at 8, Figi;1;,-andshownginorecompletely.

arranged-and bperat e d' i'nthe. usual manner.

The machine is equipped with j-inechanism for autoinatically stoppingfit,thisniechanism j comprising a belt shifterl5, Fig.4, secured on the end 'ofarod 16 and'arranged to shift the driving {beltv 17 from thej fast piilleyto 7 the loose pulleyflShor vice versa. -.The rod 16 i is mountedin thefl ame toslide long tll i .r v lnally. Adiustahly securedonithe end of this rod opposite to the shifter is a small bracket or arm which is in line with another rod 21- also mounted a): slide longitudinally in the machine. A stron spring 22-, Figs, 1, 2 and 3, is connected wit 1 this rod and tends to move it toward the right, thus operating through the arm 20; rod 16, and" shifter 1'5 to move the belt 17 from the fa stpulley 18onto the loose pulley 19 to stop the machine. Normally,howe ver, any movement of, the rod 21 under the influence of the spring 22: is preventedihy a pivoted latch 24. which. engages a sto 25'. that is, adjnstably secured on the 1'0 21.

The mechanism just described is under the control of apant movable in conjunction with the ring; rail. That is, a rod 27 is supported at its loweruendtby an arm Fig 1,, which is secured to the cnoss ,shatft 6,. so that asthis shaft is rocked by the-builder motion during the progress of the bobbin winding opera,-

t-i0n,.the izodt27 willgradually be raised until,

when the building of the bobbins, has been completed, the upper end of, said: rod will strike the latch 24:. and, lift it.. This releases the stop,25iand allows the spring 22 too enate through the connections with thebelt s lifter to shut downithe machine, Therod 27 headinstably securedtmthe arm 28 sothat it may;

be made to trip the latch 24 at any'desired point inithe rise of-the'ring'rail; 2.,

The machine also includes a. mechanism which is brought into operation aut0matically upon thetrippingof thelatoh 24 towind down thering raih This mechanism comprises a clutch, including a. driving member 30 and a driven member 31, the part 31 being mounted loosely on adrimen shaft 32, While the part 30 issplined on said shaft. This shaft carries a sprocket wheel 33 which is connected by a chain 34,-Figh 5, to a part of the drivingmechanismi ot the machine. Gonsequently,the shaft 32 isrotated continuously whilethe machine is in openation.

As showm the clutch memberfil is integral with a disk 35 and apin. 3(iiprojects from the face of this disk and isI connected by av chain 37, Figs. 1 and: 5, to, an arm 38,,Fig. 1, which is secured totthei cross shaft 6. Normally the disk 35 is idle, and it is held by gravity in substantially the position. shown, in Fig. 6 due to the fact that'thegreater part of the metal of the disk is on, the lower side of its axis as shown in. said figure. The clutch member 39 is groovedciircumferentiallsy to receive pins or rolls 39%39, Fig. 8,, projecting toward each other from a lever 40 which straddles the clutch member 30 and is rovided with a fiorwardly extending arm w ich normally bears against a collar 41 adjnstably secured on the rod 21.

The weight of the Lever 40 is so disposed that it tendsto swi ,forward,jor toward the right, Figs. 1 and ,and thus tosli'de the described, and as, shown in against movement; when this collar 41 is withdrawn, the lever 10 thenmonestheclutch member 30 into engagement with the clutch part 31, thus bringing this part into operation, and the rotary motion of the part 31 is transmittedthrough the chain b7 and its connections with the ring rail to lower orwind down said rail.

Wlhen the machine is in operation the bobbin building process manner until, the bobbins have been filled. to the desired height. At this time the upper: end of the rod 27trips the latch 24,, as above Fig. 2. The springQQ instantly acts to move the rod 21 to the right, but this movement is interruptedalmost immediately by the engagement ot the stop 25withan arm 47 pivoted at 48-, Fig. 1, and adjnstabl'y secured by a; bolt 49 to the upper end of the rod 27, so, that this arm moves inconjimction with the rin rail, Upon the release of the stop 25.by t e latch 24 therod 21 is allowed to move just far enough to permit the lever 40 to throw in the clutclr winds'down' t "e ring rail, this function being performed. by the chitclt30-31f, di'sk;35, chain 37, and; the connections between; said chain and theri'ng rail As the rm rail; moves flwnwardly, the armAT'and-rofifl? move in conjnnctionwith it and, as soon as the free end of the arm 4'? slides down pastthestop 25', the spring' 22 operates through the rod 21 and the shifter 15 to novc the belt on to the loose pulley 19, thus stopping the machine. It will be observed that while the action of the stopping mechanism. is initiated by therise of the ring rail to a predetermined elevation dnring its building movement, the completion of this operation is under the control of'the arm 27. which also moves with, orin conpmo' tion with, the ring rail 2. The pointat which i the arm 4-? permits the lielt shifting mechanism to function can be adjusted withrefer ence to the movement of the ring rail by loosening the bolt 4L9 and moving the arm 47 up or down on the rodQT.

When the disk 35 has rotated far enough to complete the depression of the ring rail, the

upper end of a latch 50 which is mounted on the outer end of the arm 5, Fi n 1, slips under the frame part 51 and locks t e ring rail in its lowermost position. A coiled spring holds the latch forward in; its operative osition. It may be swungbackward agains the act ion of the spring by stepping on the ameninto thiscondition automatically, no atten-- ib s-5,713

The parts are S proportioned that halfa revolu'tioiiioii' the disk 35 effects the Winding down of the ring rail. Justliefore'the i'lisk 35 has rotated through bring {the ring railinto,

the back, of the disk. 85, engages another cam lug v 56 on the lev erjfaO' and, forces this lever backwardly {far enough] to disengage the clutch faces of the parts 30 and31. This moveni'e'nt sivings the upper end of'thef lever atOftoivard the1left,"Figs."1- and far enough lQpe'rmitithe latch 57 to drop in behind the end ,of the lever, asclej'arly sho wn i Fig.

and thus lock theclutch in itsd'i'sengaged or inoperative position, i

The machinei'now in condition for the doiiing operation, and it has been'brought tion on the part of the operator having been required up to this point. After dofling, the

operator WindsdoWn the builder motion in the usual manner, and then throws the usual hand lever (not shown) which is connected with the rod 16 to move this rod toward the,

'left,'Fig.1, far enough to shift the belt 17 back on to the fast pulley 18. At substantially the same time the operator releases the Y latch '50 thus starting the machine nto opera tion again.- As the rod 16 is moved toward the left the bracket 20 engages the end of the rod 21 and moves it toward the left, thusre-.

storing the parts to the positions in Which they are shown in Fig. lwvith the latch 24 engaging the stop25 and the collar il bearing against the upperend of the lever 40. 1 Asthe' collar l1 moves toward the leftit lifts the latch 57 out of engagement with the end of the lever 40. e

This invention 1 thus provides a mechanism for winding down the ring rail'which is entirely automatic in its action, which is very simplein construction and can be manufactured very economically. The mechanism is of a very sturdy construction, is not liable to get out of order, and requires a minimum of the amount of yarnwhich bases of thebobbins l the best en'ibodiment of my invention that-I- care and attention on the part of the operator. It should be noted that in this machine the full bobbinstop motion simply initiates the operation of the stopping anduind down mechanisms, but the actual stopping of the machine is under the control .of the arm 4L7 which moves in conjunction with the ring rail that thc machine is not permitted to stop until the ring rail has been wound'down to a predetermined point.
